Container — Container Technology Reference

Quick-reference skill for container internals, image formats, and runtime mechanics.

When to Use

• Understanding how containers provide process isolation
• Debugging container networking, storage, or resource issues
• Learning OCI image specification and layer mechanics
• Comparing container runtimes (runc, containerd, CRI-O)
• Optimizing Dockerfile builds for smaller, faster images

Commands

intro

scripts/script.sh intro

Overview of container technology — history, OCI standards, and architecture.

namespaces

scripts/script.sh namespaces

Linux namespaces — the isolation mechanism behind containers.

cgroups

Control groups — resource limiting for CPU, memory, I/O, and PIDs.

images

Container networking — bridge, host, overlay, and CNI plugins.

storage

scripts/script.sh storage

Container storage — volumes, bind mounts, and storage drivers.

runtimes

scripts/script.sh runtimes

Container runtimes compared: runc, containerd, CRI-O, Kata, gVisor.

security

scripts/script.sh security

Container security — capabilities, seccomp, AppArmor, rootless mode.
